Surface Quality Analysis of Grinding Scratch Dimensions of Building Structural Steel under Ultrasonic Vibration
Ultrasonic-assisted grinding method is a new grinding technology that adds ultrasonic vibration to the traditional grinding processing method,which can significantly improve the processing performance.Take structural steel as structural steel,set up different scratch depth under ordinary ultrasonic vibration scratch test.The results show that a large amplitude is formed during ultrasonic vibratory grinding scratches,and the scratch depth is significantly increased.The increased ultrasonic amplitude results in greater input energy in the system,which enhances the material removal rate.The vibratory impact of the diamond indenter produced persistent crack defects located at the bottom of the scratch with the regions on both sides.As the amplitude increased,longer scratches were formed during intermittent impacts,increasing the scratch depth and reaching a relatively stable scratch depth that exhibited brittle removal characteristics.
